Photogrammetry combines 2D photos into detailed 3D models, point cloud and orthomosaics.
High resolution photos are acquired with an extremely high level of overlap. This would be used together with the georeferencing metadata and ground control points. With the increased overlap, the software is able to identify common points throughout several images automatically, and triangulates them together to create a 3D space of the environment.
After more reconstruction of the 3D model is complete, it would result in 3D textured meshes, dense point clouds and digital twin.
Photogrammetry would be able to work with several buildings which include rock face mapping, building inspection and landslip analysis.
